VOICE-REPRODUCING DEVICE.

Application filed June 26, 192; Serial No. 647.916.

This invention relates to voice reproducing devices and more particularly to a novel and improved device especially adapted to be incorporated in the body or form of a doll whereby when the latter is turned, the sound reproducing mechanism will be actuated.

One of the objects of my invention is to provide a voice reproducing device wherein the pitch of the sound is intermittently varied when the device is actuated so as to reproduce the sound to simulate that of a crying child in uttering the short and'long syllables, Manna.

To enable others skilled in the art to fully comprehend the underlying features of my invention that they may embody the same in the various modifications in structure and relatidn contemplated, drawings depicting a preferred form have been annexed as a part of this disclosure and in such drawings, similar reference characters denote corresponding parts throughout all the views, of which,

Figure 1 is a vertical sectional view through the device.

Figure 2 is a similar view showing the same inverted and the bellows extended.

Figure 3 is a sectional view taken substan-' tially on the line 3+3 of Figure2.

Figure 4; is a similar sectional view when the weight is in another position on the spindle. I i

Figure 5 is a detail of the disc carrying the reed on the weight.

Referring now to the drawings, wherein like reference characters designate corresponding parts throughout the several views, 5 designates the conventional type of housing adapted to be secured in a form such as a doll, said housing having an annular flanged top 6 with openings 7 therein to permit of the passage of air to the interior of the device. A flexible bellows 8 overlying the bottom edge of the housing is secured thereto and held in osition by a flanged bottom 9 so that said bellows may be extended when the device is inverted to the position shown by Figure 2 of the drawings The said bellows 8 is connected to a hollow weighted element 10, which is substantially frusto-conical in shape and provided with an inlet aperture 11 in the top thereof. The said weighted element 10 is additionally provided with a central aperture so that it may slide on a central spindle or guide 12 secured between the top and bottom of the lVithin the hollow portion of the weight 10, a seat is provided for a disc 16 supportmg a reed, which disc is preferably cemented or otherwise rigidly secured as at 17 a in said seat, so as to operate with the weight. The disc 16 above referred to, is formed with a central tube 17 of a diameter justslightly larger than the diameter of the spindle 12 as its greatest thickness, said tube 17 extending as shown, above and below the disc 16, more clearly illustrated by Figure 5 of the drawings. The tube 17 is further pro vided with opposed recesses 18 to permit of the entry of air and the exit of the sound from the bellows 8. The angularly disposed reed 19 secured and held by the disc 16 extends upwardly within the hollow portion 20 of the weight and into the bellows 8.

Vhen the device is inverted from the position shown b Figure 1, so that the bellows 8 are extendec, air will be drawn into the interior thereof through the aperture 11 and. the reed 19. As the device is again inverted to its originalposition and the sound or air escapes, the volume will be varied as the openings 18 of the tube carried by the disc move past the reduced portions of the spindle 12.1 A slight volume of air will escape through the reed 19 when the tube 17 moves on the second portion of the spindle and consequently, the length of the sound and the volume emitted will depend upon the distance and thickness of the spindle'on which the disc 16 is guided during the falling movement of the weight 10. g

It will be observed that the section 15 of the spindle is of a length slightly less than that of the portion 141, so that as, the bellows is compressed the sound, Ma-ma will occur. The initial slight movement of the weight before the tube 17 and particularly the openings 18 move past the reduced portion 15, producing the sound of the letter m, which, of course, broadens out to produce the sound of Ma which is again interrupted to simulate the sound of the letter m and thenagain the protracted sound of the last syllable of Ma-ma and finally a longer, protracted sound of the letter m.

i It Will thus be seen from this construction that by varying the size of the openings in thetube 1.7, or the diameter of the spindle 12 at various points throughout its length, that different sounds may be possible, each time the device is inverted. It will also be seen "that the spindle 12 extends through the sound chamber 20 into which the sound from the reed pipe 19 issues and also through the weighty head member 10 whereby it extends through an opening in one wallo'f the sound chamber through which opening the sound is adapted to issue. The spindle 12 not only guides the weighty member in its back and forth movement in the casing but acts as a valve for opening and closing the opening from the sound chamber as the reduced portions and non-reduced portions of the spindle pass the opening. As will be seen from Figs. 1. and 2 the non-reduced portions have portions which taper into the reduced portions; and the non-reduced portions are integral with the spindle thereby making the arrangement cheap but efficient in construction and operation. Furthermore the reed pipe 19 extends from the air chamber formed by the bellows, through the plate 16 and into the sound chamber and lies at an angle in-' clined to the spindle and the direction of movement of the weighty member whereby a relatively long reed pipe may be used without its extending below or beyond the face of the weighty member. The tubular mem ber 17 which surrounds the spindle to aid in guiding the weighty member on the spindle, not only is secured to the plate 16 but also extends into one wall of the weighty member and is apertured to permit of the escape of sound therethrough. V y

While I have illustrated and described my invention with some degree of particularity, I realize that in practice various alterations therein may be made. I therefore reserve the right and privilege of changing the form of the details of construction or otherwise altering the arrangement oi the correlated parts without departing from the spirit of the invention or the scope of the appended claims. I

Having thus described my invention what I claim as new and desire to secure by United States Letters Patent is:

1. A sounding device having in combination a casing, an air chamber therein, a wcightymember movable by gravity within the casing to compress said air chamber, said weighty member being hollowed out on the side adjacent the air chamber to form a sound chamber, a plate substantially closing said sound chamber to said air chamber and a reed pipe carried by said plate and extending therethrough at an angle to the direction of movement of said weighty member, a spindle extending through the sound chamher and fixed with respect to the casing a tubular member secured to said plate and surrounding said spindle to aid in guiding the weighty member on the spindle, said tubular member extending into one wall of the weighty member and being apertured to permit of the escape of sound therethrough.

2. A sound device having. in combination, an air chamber, a weighty member movable by gravity to compress the air in said air chamber. said weighty member being hollowed out on the side adjacent the air chamber to form a sound chamber, a plate substantially closing said sound chamber to. said air chamber, and a reed pipe carried by said plate, a spindle extending through said sound ch amber, a tubular member secured to said plate and surrounding said spindle, said tubular member extending to the opposite wall of the weighty member and being aper= tured in the sound chamber to permit the escape of sound therethrough.

In testimony whereof I afiix'my signature.
